Extended Data Fig. 2: Detailed experimental setup.
From: Sensitive vectorial optomechanical footprint of light in soft condensed matter
Extended version of the illustrative experimental setup shown in Fig. 2(a). BS: non-polarizing beamsplitter for the probe beam. Note that Fig. 2(a) only summarizes the main instrumental ingredients used in practice. Namely, the lens L2 in Fig. 2(a) is an imaging lens for the probe beam in order to observe the director field at the mid-plane of the liquid crystal sample, which corresponds to the 10 × objective lens as shown here. Also, the lens L3 in Fig. 2(a) refers to a collimating lens for the pump beam, which corresponds to a lens system made of a 10 × objective lens followed by a plano-convex lens (f = 100, 150, 200 mm) as shown here. See Methods for details.
